Novel Bio-based Plasticizers for Poly(Vinyl Chloride) Poly(Vinyl Chloride) is the third most synthesized and utilized commodity plastic. While its unplasticized form is used extensively in construction materials because of its toughness and rigidity, it is also desirable for biomedical and packaging applications due to its sterility and chemical resistance, requiring plasticization which accounts for 80% of the world's plasticizer usage.

Oxidative Coupling Reactions of Phenols and Azines Via Cationic and Radical Intermediates The photochemical oxidative coupling of phenols with a range of coupling partners will be described. Even though the reaction likely involves radical intermediates, selectivity can be controlled by selecting coupling partners with different oxidation and nucleophilicity profiles. In addition, the use of donor acceptor complexes permit coupling with partners that have lower oxidation potentials than the phenols. The use of solid photocatalysts and the removal of product to prevent overoxidation will be also be outlined.

Student Reasoning about Molecular Structure and Behavior in Organic Chemistry Reasoning about structure, reactivity, and chemical processes is a critical competency for organic chemistry students. Yet many students cannot fully interpret or explain the underlying chemical reasoning behind the many representations we use to depict chemical phenomena. We need to know more about how to scaffold students reasoning as they learn to translate and make meaning of the symbols and language of organic chemistry.

Integrating Field Studies and Laboratory Experiments to Investigate the Processes and Climate Impacts of Atmospheric Pollutants Atmospheric pollutants, ranging from traditional organic aerosols to emerging contaminants such as nanoplastics and per- and polyfluoroalkyl substances (PFAS), play critical roles in air quality, climate forcing, and environmental health. Yet their sources, atmospheric transformations, transport pathways, and impacts remain poorly constrained.

Catalytic Ring Strain Release for the Synthesis of Heterocycles and Natural Products Cycloaddition reactions have been recognized as a robust method to construct carbocyclic or heterocyclic systems in a highly convergent manner through a concerted or stepwise mechanism since the original discovery of the Diels-Alder reaction. N-Heterocyclic compounds are considered “privileged structures” in pharmaceutical and medicinal chemistry for their core structure being present in many biologically active molecules and building blocks.
